Petro K. Improving the efficiency of biogas production by co-digestion of manure with maize silage

The thesis is devoted to the study of efficiency of anaerobic co-digestion of manure with maize silage, justification and choice of the rational regimes of biogas plant operation from technological and economical points of view. It was experimentally studied the influence of the addition of different share of maize silage to manure as well as the influence of initial organic matter concentration in reactor on the yield of biogas and methane while digesting periodically. Potential of methane generation from few domestic varieties of maize was investigated. The modified method for the evaluation of kinetic parameters of methanogenesis based on the yield of methane in periodical process, as well as the method of evaluation of methane yield indicators when digesting in continuous stirred tank reactor with the use of the evaluated kinetic parameters were offered.
